wordpress affiche 2 fois le titre des pages et articles

The upper title that you have marked in the screenshot is displayed at this point by the theme you are using. Their support can be found here: https://projectdmc.org/support/theme/mantra/

You can also suppress the output yourself with the following customised CSS:

#content h1.entry-title {
  display: none;
}

You would have to insert this under Design > Customiser > Additional CSS.

Merci beaucoup pour votre réponse rapide et efficace. Cela fonctionne parfaitement sur les articles et les pages excepté sur la page d’accueil du site ! https://urlz.fr/p3jP

Avez vous une explication ?

Encore merci beaucoup…

There, curiously, it is an h2. The CSS code would have to be updated accordingly:

#content h1.entry-title, #content h2.entry-title { 
 display: none;
}

Please note that this is only a visual adjustment. Suppressing the headings in this form may have a negative effect on the ranking of your page by search engines. Optimal customisation should be possible through the support of the theme you are using.

Merci encore, cela fonctionne et je vais surveiller s’il y a une influence sur les moteurs de recherche.

Bonne journée
